SummaryCLSK has gained our trust as it kept its promise to achieve 3.2 EH/s capacity back when its capacity was only 0.35 EH/s in Dec 2020.Analysts claim that CLSK is undervalued based on market price to capacity ratio, but we found no such support after considering its expected future capacity and Bitcoin reserves.CLSK's Bitcoin reserve severely trails competitors due to high costs in the past and unwillingness to dilute shareholders, this will subtract CLSK's ability to benefit from a bullish Bitcoin reversal.Bitcoin is now trading below CLSK's cost of sales (electricity + depreciation) per BTC, should Bitcoin fall below the $10,000-$14,000 range, CLSK risks insolvency.We retain our stance to invest in Bitcoin rather than miners.IntroductionCleanSpark (CLSK) is one Bitcoin (BTC-USD) mining company that did not catch our attention but was highly recommended to us by our readers.
